Unfortunately, this post won’t give you the secrets to nailing every job interview you ever have, but it’ll probably give you a better idea than what you already have, so here we go.
Step 1. Don’t worry about being nervous
A good interviewer will understand that if it’s a job you really want, you’re going to be nervous, it shows you care. But that certainly doesn’t mean you shouldn’t be confident. Which brings me to step 2.
Step 2. Show your passion
A good interviewer will look for passion in the interviewee. If you’re feeling nervous and suddenly get passionate about a topic that someone in your field would never even understand, like why you should use ++i instead of i++, or why you should give ‘i’ a name in the first place (for god sake programmers, do yourself a favour and spend an extra 3 seconds to name your damn loop variables and save yourselves the pain of staying up until 3 am 7 days a week trying to meet a deadline because you accidentally hit a j instead of an i and have a ridiculous amount of bugs and you have no idea what’s causing them).
Step 3. Know what you’re talking about
I don’t just mean at a complex level that only someone decent/good in your field would understand. Explain everything at a basic level that someone without any experience would understand. This shows that you not only know what you are doing, but know why you are doing it. For example, I would explain that using ++i instead of i++ as a variable in a loop is 20% quicker as i++ makes a copy of i, updates the copy, then sets the original i to the value of the copy and if the loop has a loop inside of it, j is used instead of i and after hours and hours of programming, i can look a lot like j and they are very close on the keyboard so by not naming those variables, you leave yourself open to making a lot of easily avoidable mistakes.
Step 4. Show initiative
This is a tough one, as it isn’t something you can actually do in an interview, it’s something you need to have done in the past. You don’t necessarily need work experience in your chosen field to prove that you can show initiative. Talk about group projects during your education, or about times in any other line of work where you took a leadership position, in order to get something done. Like the time your manager didn’t show up to work because he drank too much the night before and was really hungover, so you took charge and told all the other part time staff members what to do for the entire day, even though you didn’t get manager pay, but hey, that’s retail for you.
